SAN should be accepted for Sino-atrial node because it would be in a biology exam

Also, A, C, G and T are organic bases. Base PAIRS are A and T, G and C...

Can light-independent be accepted? I tried some real creative ways of spelling that one but didn't think of adding "reaction"

-SAN or SA node should be acceptable

- Nitrogenous bases or DNA bases should be accepted - base pairs as an answer is incorrect.

-Calvin cycle, Calvin-Benson cycle or carbon fixing are also acceptable answers for light independent reactions.

- Neurone is spelled neuron.

- Acetyl CoA is also an acceptable answer.
